While we're on the topic, Xenophon's "Anabasis" is probably both the greatest military memoir of all-time and the greatest adventure story of all-time.
Heck, maybe also a candidate for greatest learning-on-the-job and leadership story too.
It's really an incredible work. The "Why am I lying here?" monologue still gives me chills.
Ok, I wanted to read "Anabasis" for quite some time, but never actually gotten myself to it. However, you provided the final nudge, I'm already past page 10.
